Hello, Nat077!
Yes, I do!I have worked out that the answer is maybe 3/10
Do you think this is correct?
There are: .$\displaystyle 5 \times 4 \:=\:20$ outcomes.
. . And six of them have a sum less than 5: .$\displaystyle (1,1),\1,2),\1,3),\;(2,1),\2,2),\3,1)$
$\displaystyle P(\text{sum}< 5) \:=\:\frac{6}{20} \:=\:\frac{3}{10}$
. . . Good work!
